Show Suggested Answer Hide Answer
Suggested Answer: D

Cloud Workstations provides a secure way to preview web applications using built-in preview links, which expose internal ports only via authenticated and authorized access --- no public IP exposure required.

''To preview your app, click the preview icon in the Code OSS panel, which securely tunnels the service to your browser.''

--- Cloud Workstations - Previewing your app

This adheres to Google's security best practices by avoiding public IPs or manual tunneling while enabling developer efficiency.

Wait, can you really access it just by clicking a link? Sounds too simple!

Running the gcloud compute start-iap-tunnel command sounds familiar; I think we practiced that in a similar scenario last week.

I feel like allowing public IP addresses could expose us to risks, so that option seems wrong.

I think the preview link in Code OSS might be the easiest way to access it, but I'm not sure if it follows the security practices we studied.

I remember something about using IAP tunnels for secure access, but I'm not entirely sure how to set it up correctly.
